Just as we heard earlier, Nintendo's overhauling its loyalty program, Club Nintendo, offering users downloadable games for the 3DS and Wii in addition to previously-offered swag like notebooks and posters. The relaunched site is live now and is offering four games: Super Mario Kart and Fluidity for the Wii, 3D Classic: Xevious and Mario vs. Donkey Kong: Minis March Again for the 3DS. Typically, these games would set you back anywhere from $6 to $12. While the program has a redesigned site and improved rewards, it works in the same fashion as before: register games and systems, answer a survey now and again, and get rewarded with "coins" that you can redeem for rewards.If you're interested in redeeming some hard-earned coins for these games, you have until January 10th — at that point, Nintendo's pulling the games and putting new ones in their place. Nintendo's even planning on asking members about the games it offers, so keep your eyes peeled if you want to influence future rewards.
